Before you spend hundreds of dollars on chiropractic pillows, consider this easy trick recommended to me by a physical therapist. Roll up a bath towel evenly so that the width of the towel is close to the width of your shoulders. (To see a visual scroll down and watch the video) Slip it into your pillow case lengthwise so that the towel is at the base of your neck when you lay flat on it. As you can see from the diagram below, your neck requires extra support, or else you will be spending an average of 8 hours a night straining your muscles.
